We use Threshold Signature Scheme (TSS) technology to give you full access to your wallet without the need for all 5 of your Guardian devices to be online.
Key splitting ensures your private key is concealed and unreachable at all times. TSS is how you bypass the restrictions to use your wallet without relying on all of your Guardian devices to be online.
To use your wallet, you only need 3 out of 5 guardian devices to be online, which is normally you (1) and Gridlock (2). In the event that Gridlock goes down, your guardians are there to ensure you can recover your funds.
